POST /api/listing accepts a JSON body with the manifest fields, a
reference to a signed scan report from /api/upload, and a BIP-137
signature. Before the row lands in SQLite the service verifies three
things:
1. the attached scan_report was signed by this service, is for the
exact (hash, size) the listing claims, and the verdict is clean —
a publisher cannot swap in a different file's clean report;
2. the publisher's signature recovers to a valid cashaddress, and
that address matches the on-chain owner of the publisher's BNS
name (gateway /api/name/<name>) — recovery alone is never enough
per [[recovery-is-not-verification]];
3. the usual shape checks: category in the allow-list, sha256 is 64
hex, download URL is http(s), slug matches [a-z0-9-]{1..64}, body
under 1 MiB.
GET /api/listings and GET /api/listings/<publisher>/<slug> are read-only
endpoints the browse milestone will render from.
MOCK_BNS_OWNER=<cashaddr> short-circuits the gateway call for local
testing without a chipnet gateway reachable — same pattern as MOCK_SCAN.
Dependencies:
- @bitauth/libauth, for the secp256k1 primitives behind BIP-137 recovery
and the cashaddress encoder. Same primitive Argus's registrar uses, so
signatures from Argus-compatible wallets verify unchanged.
- node:sqlite (ships with Node 22+) for the listings DB — one file next
to the service, WAL journaling, no native build step. engines bumped
to ">=22".
Lifted service/lib/sign-message.js from Argus so Prometheus does not
have to pull the resolver's whole dependency tree in for one verifier.
Removed its NETWORK import; the default address prefix comes from
BNS_NETWORK=chipnet|mainnet instead.
INTERIM: no APS1 record on chain yet. The signed row IS the listing;
when APS1 is defined cross-session the service will add an on-chain
publish step that points at the same signed manifest. The browse and
admin milestones can proceed against this DB in the meantime.
scripts/test-listing-roundtrip.mjs drives the whole flow end-to-end
with a deterministic test key, so a sanity check is a two-command
sequence: start the server with MOCK_SCAN=clean + MOCK_BNS_OWNER=<the
test address>, then run the script. Negative paths (fake scan report,
bad category, duplicate slug) also verified by hand.
